| A hardware address is a six-byte data-link layer address coded into a network interface adapter, while an IPv4 address is a 32-bit software setting supplied by a server or a network administrator. |

| What is the difference between a hardware address and an IPv4 address? |
|
|
Term
| On a TCP/IP network, an application issues function calls to an application layer protocol, which packages the application data to be transmitted over the network and passes it down through the layers of the networking stack. At the transport layer, the TCP or UDP protocol encapsulates the application layer data by adding a header containing the port number and passes the packet down to the network layer. At the network layer, IP adds its own header containing the destination address for the packet, and passes it down to the data-link layer. At the data-link layer, Ethernet completes the encapsulation process by applying a frame containing the address of a router on the local network. |
